Need help!

I wanted to step into the usage of Visual Basic in Visual Studio 2008 (well, actually, `wanted` is not the right word here.. but, anyway, my job forced me to do that), but I stumbled upon such an error when trying to open an existing VB project.. 😦

I surfed the net then and discovered I am not alone in this situation.. However, everybody says reinstalling does not solve the problem.. What can I do now? Any VS VB specs here? Help me if you can, please!

What Does This Function Do?

1. Please, give your answers in comments – what does the function written below do:

a)      recognizes prime numbers

b)      recognizes prime numbers in interval [100;999]

c)      neither a) nor b) is correct

d)      other variant (please, specify)

2. And the second question is – is this function a correct solution if the task is as follows: `Please, write a function that recognizes all the prime numbers consisting of exactly 3 digits`:

a) yes

b) no

The function (in C++):

bool f(int x) {

 for (int y=2;y<x;y++)

  if (x%y==0) return false;

 return true;

}

P.S. I wish all of you wrote your thoughts in order to make a student of mine understand the essence of the thing!
